RockDoor has been the driving force behind composite door technology for over 20 years.
During this time, more than half a million doors have been produced in their Lancashire innovation and production centre.

They use nickel-coated solid brass for their hook locks, high impact PVCu skins to resist cut-through, carbon fibre to reinforce their inner frames and a unique S-Glaze system that locks the glass into your door for life. It means RockDoors can’t be forced open.

And because every RockDoor is made-to-measure rather than mass-produced to a standard shape before being trimmed to size, it’s an exact fit for your home.

Nearly 70% of burglaries involve forced entry through the front or back door. Their nickel-coated solid brass hook locks slide into steel keeps that run the full length of the outer frame. It means your RockDoor can’t be forced open.

For 20 years RockDoor have been investing in the technology needed to build you the toughest, safest and most energy efficient doors available. Their locking systems and carbon fibre reinforced frames protect more than half a million UK homes.


On the face of it, Formula 1 racing cars, orbiting satellites and fighter jets would seem to have little in common. In fact they all rely on carbon fibre to guarantee that they’ll be able to withstand phenomenal force. No surprise then, that RockDoor chose it to reinforce your RockDoor.

When strength matters when it comes to making sure no-one can force their way into your home, carbon fibre is also the material of choice when it comes to maximising thermal efficiency.


S-Glaze for Security
Contrary to popular belief, burglars prefer to quietly unclip and remove glazing panels in front and back doors rather than smash their way through them. And with most composite doors, it only takes a minute or two. In RockDoors, the double-glazing is instead part of the door itself. It can’t be removed.

S-Glaze for Thermal Efficency
Because each RockDoor’s specially-coated double-glazed units are bonded to the door during the manufacturing process, they’re locked in for life. It means no air can pass through – a common problem for manufacturers who instead use glazing cassettes. It means RockDoor can achieve the highest possible energy efficiency rating A++.


RockDoor has been granted numerous accreditations – including PAS 24 and Secured by Design.
